This action may be shown by the apparatus… … Fig. 203. few oscillations will come to rest in a position sensibly atright angles to the current. That it does not take a posi-tion absolutely perpendicular to that of the current, is be-cause of the directive force of the earth, which partiallycounteracts that of the current. The direction…
